[0023] Please refer to Figure 4, filter oil assembly 2 includes filter oil cavity 201, the outer surface of filter oil cavity 201 is provided with a plurality of filter oil holes 202, and the upper end surface of filter oil cavity 201 is provided with an annular connecting groove 203, and the annular connecting groove 203 is matched with the annular connecting thread 104, when the annular connecting groove 203 is coincided with the annular connecting thread 104, the filter oil assembly 2 is connected with the anti-backflow assembly 1, and the filter oil cavity 201 is communicated with the circular frame 101.

[0024] Please refer to Figure 5 , the blocking assembly 3 includes a second circular frame 301, the outer side of the second circular frame 301 is provided with a rectangular guide groove 302, the rectangular guide groove 302 is connected with a rectangular floating block 304 in the inner cavity, the upper end of the rectangular floating block 304 is connected with a circular lifting rod 305, the upper end surface of the circular lifting rod 305 is connected with a first circular plug 306, and the two sides of the end of the circular lifting rod 305 towards the first circular plug 306 are connected with a second rectangular connecting block 307, the end of each second rectangular connecting block 307 away from the circular lifting rod 305 is connected with an arc-shaped blocking plate 308, the upper end of the two sides of the second circular frame 301 is connected with a first rectangular connecting block 303, and the first circular plug 306 is matched with the first connecting pipe 102, and the arc-shaped blocking plate 308 is matched with the inner cavity of the circular frame 101, when the first circular plug 306 and the arc-shaped blocking plate 308 respectively block the first connecting pipe 102 and the second connecting pipe 103, the first controller will be closed to the oil conveying pipe connected with the connecting pipe.

[0025] Working principle: when multiple agricultural machinery needs to filter oil, the oil is conveyed to the inner cavity of the circular frame 101 through the first connecting pipe 102 and the second connecting pipe 103, then the filtered oil is conveyed to the agricultural machinery through the filter oil hole 202 on the surface of the filter oil cavity 201, and the agricultural machinery continues to operate;

[0026] And when the filter oil hole 202 is blocked during long-time filter oil operation, the oil will gradually accumulate in the filter oil cavity 201, and as the oil in the filter oil cavity 201 gradually accumulates, the rectangular floating block 304 will move upward along the rectangular guide groove 302, thereby driving the circular lifting rod 305, the first circular plug 306, the second rectangular connecting block 307 and the arc-shaped blocking plate 308 to move upward, until the first circular plug 306 is coincided with the lower end outlet of the first connecting pipe 102, thereby blocking the first connecting pipe 102, thereby avoiding the oil in the first connecting pipe 102 from continuing to leak out;
